can you explain how a full system can be legal?

 

full system as I know means there is no catalytic converter, so how can it be legal?

 

@actionong

Hope you are asking sincerely and not just trolling.

It's simple if you understand the mechanics behind it. The certification requires 2 main types of tests; emissions + noise.

 

Between these, the noise category is divided into pass-by noise, and stationary noise.

Broadly, CO and HC are measured for emissions.

 

HC Emissions and pass-by noise is a non-issue as Singapore does not include this in their tests. You merely provide ECE 22.05 certification indicating acceptable output.

Your CO output will likely pass even without a catalytic converter if you're using a modern 4-stroke engine since the Euro I standard is pretty old and limits are generally outdated. Most of the world has gone up to between Euro III to V standards.

The troublesome thing in Singapore is the stationary noise test, which few countries do world wide. Just measure your own decibels to make sure the system can actually pass before you bring it in for testing.

 

If you bother to get the testing process done most modern engines will pass with most baffled exhaust systems designed for the vehicle.

 

Once you have ensured you have the documentation in place and you have done your own installation. You can then tow the vehicle down to LTA for testing. If your documentation is in order, and your modification performs within LTA specified limits, then boo ya you get a cert and a legal system.

 

The process is not difficult, just time consuming.

If you are genuinely interested you can always call LTA and the officers can talk you through the process in greater detail, including what forms to fill in and the documents you need etc.

Noted with thanks. Can consider a full system in future
